Beit known that I, NEWTON .ViLooxoN, a

citizen of the United States, residing at Chif cago, county of Cook,State of Illinois, have i invented a certain new and useful Improvementin Dumping-Cars; and l declare the following to be a full, clear, andexact descrip'- tion of the invention, such as will enable othersskilled in the art to which it pertains to make and use the same,reference being had to the accompanying' drawings, which form a part ofthis specification.

My invention relates in general to d umpingcars, and more particularlyto alatch for closing the side-boards of a car of the tilting-body typetightly against the bottom thereof when the body is swung into ahorizontal position.

In d umping-cars of the type referred to it is customary to so supportthe side-boards that the one on the side of the carfrom which thematerial is dumped is permitted to swing outwardly, but is held in anelevated position when the body tilts downwardly. Then the body is swunginto a horizontal position, it frequently happens that the side-boardfails to automatically close, thereby causing inconvenience and loss oftime.

The primary object of my invention is to provide a dumping-car of thetilting-body type in which the side-board on the dumping side of the carwill be automatically closed and securely locked against the body of thecar when the car is swung into a horizontal position after dumping.

A further object of my invention is to provide a latch for automaticallyswinging the side-board of a dmnping-car into closed position andtightly locking the same against the car-I )ody when the latter is swunginto horizontal position.

A further object of my invention is to provide an improved latch for adumping-ear which will be simple in construction, inexpensive inmanufacture, and eflicient in operation.

)ly invention, generally described, consists in a tongue rigidly securedto and projecting downwardly from the lower edge of the sideboard, neareach end thereof, of a tilting dumping-car, a keeper fixed to the bodyof the car l l l in position to receive the tongue when the carbody isswung into a horizontal position, and a latch pivotally mounted in thekeeper, the upper end of which projects outwardly when the car-body istilted and serves as a guide to direct the tongue into the keeper whenthe body swings upwardly, the lower end of the latch projecting into thepath of the tongue through the keeper, so as to be engaged by thetongue, thereby swinging the upper end of the latch inwardly intocontact with the side-board and forcing the same tightly against thecar-body.

My invention will be more fully described hereinafter with reference tothe accompanying drawings, in which the same is illustrated as embodiedin a convenient and practical form, and in which- Figure l is anelevational view of a portion of the dumping-ear, showing the side-boardclosed ,against the body; Fig. Q, a view similar to Fig. 1, showing thebody in an inclined position; and Fig. 3, an elevational view lookingfrom the right in Fig. l.

The same reference characters are used to designate the same parts inthe several ligures of the drawings.

A designates a portion of the end of a car- -body of the tilting' type.

fr designates the bottom of the car-body; A, an angle-beam extendinglongitiulinally beneath the bottom of the car, the end of which projectsbeyond the end of the car and serves to support the lower end of a braceu', which extends upwardly on the outside of and adjacent to the edge ofthe end A of the carbody.

A Vdesignates an angle-plate secured to and projecting along' the edgeof the end A of the car-body against which the side-board of the ear isswung.

B designates one of the side-boards of the car, which is pivotallysupported at each of its upper ends by a bolt ff, mounted in thebifurcated outer end of a support C. The support C is mounted in theusual manner upon the car structure and serves to support the side-boardon the dumping side of the car in an elevated position when the car-bodyis tilted.

IOO

' board B. Any suitable means may be provided for fastening the keeperto the anglebeam Azsuch, for instance, as bolts d', extending throughlaterally-projecting'ears Z and through the vertical portion oftheangle-V beam A2.

A swinging' latch E is located Within the keeper D and pivotallysupported upon a r'od c, the latter extending through openings in theside walls of the keeper and having nuts secured on its ends. Theportion of lthelatch E above its fulcrum is somewhat extended, so thatwhen the body of the car is tilted it will project outwardly aconsiderable distance. as indicated in Fig. 2. below its fulcrum extendsinwardly at an angle to the upper portion of the latch, so as to extendacross the opening through the keeper when the upper portion of thelatch is tilted outwardly, as shown in Fig'. 2. The top of the keeperserves as a stop to limit the outward swinging of the latch.

Secured to and projecting below the side board of the car at each endthereof is a tongue preferably formed integral with the strap B. Thetongue Z/ is of a width adapted to be received Within the keeper D andis located in the same vertical plane as the latch E.

The operation of my invention is as follows: The body of the car istilted by any wellknown means to the side to which it is desired to dumpits contents. as, for instance, B--is held in an elevated position byits supporting-bar C when the 4corresponding side of the car-body swingsdownwardly, such relative movement between the side-board and car-bodybeing' permitted by the downward movement of the keeper D away from thetongue L'. I/Vhen the contents of the car have been dumped, the body isvswung into a horizontal position, and in the movement theupwardly-rising side portion of the latch E above its fulcrum engagesthe lower end of the tongue and guides the same into the keeper D,thereby insuring' the closing of the side-board even though it may haveswung outwardly at its lower edge a considerable distance away from thecar-body. The lower end of the tongue after being guided into the keeperengages the inturned lower portion e of the latch and swings the latchinto an uprig'ht position, so that the upper end thereof is forced intocontact with the The portion of the latch A The side-board-v strap Bl,and thereby retains the side-board in closed position against thecar-body. My

improved latch therefore not only insures the closing of the side-boardof the car, but also prevents the same from rattling when closed.

It will of course be understood that latches such as described arelocated adjacent to each edge of each of the side-boards of the car andthat for convenience I have merely shown a single latch and the adjacentportions of the dumping-car.

From the foregoing description it will be observed that I have inventedan improvement in dumping-cars whereby the automatic closing of theside-board at the side of the car from which the material has beendumped is insured and the side-board is forced tightly against theadjacent edges of the end-boards of the car-body, thereby tightlyclosing the car and preventing rattling of the side-boards.

Thile I have described more or less precisely the details ofconstruction, I do not wish to be understood as limiting myself thereto,as I contemplate changes in form, the proportion of parts, and thesubstitution of equivalents as circumstances may suggest or renderexpedient without departing from the spirit of my invention, and while Ihave disclosed my invention as embodied in a dumping-car it is obviousthat it may be also embodied in a dumping-cart or other form of vehicleor in a dumping-receptacle of any construction.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a dumping-receptacle comprising a tilting' body and apivotally-supported sideboard, the combination with a tongue dependingfrom the lower edge of the side-board, a keeper secured to the body inalinement with said tongue, and means pivoted in the path of movement ofsaid tongue for guiding the same into the keeper when the body is swunginto a closed position.

2. In a dumping-car comprising' a tilting bod yand a pivotally-supportedside-board, the combination withatong'ue depending' from the lower edgeof the side-board, a keeper secured to the body in alinement with saidtongue, a
